Authors: Mulyana Budi , Rohman Rohman , Purwanto Ris Hadi
Published: September 2019

Estimation of the potency of community forest is usually done with the census approach for each forest. Sampling methods to estimate the potency of community forest are still rare. The size of community forest is relatively small, scatter, and less irregular shape, therefore the estimation of community forest potency using sampling plot is difficult to apply. The approach of sampling without a plot (plotless/ point sampling) was cheaper and faster compare to the method of sample plots and direct measurement (census) in predicting basal area. The objective of this research is determining the difference in the average value of basal area using direct measurement of stand (census) and point sampling methods. The research was carried out for 4 months in 30 community forests at Kemuning Village, Gunungkidul District. Materials used to estimate basal area with point sampling method were Spiegel Relascope and Bitterlich Stick with the value of Basal Area Factor 1. Parameters measured were diameter at breast high (dbh) for census method and the number of trees were categorized in or border for point sampling method. The result was analyzed statistically using unpaired t-student. The result showed that the average of basal area of tree in community forest with point sampling method were no significantly different from the average of basal area with census method (α = 1%). Therefore, the point sampling method can be considered as a tool in inventory at community forest

Published: September 2019

Deforestation that occurs causes a decrease in soil fertility. Knowing soil fertility in the landscape will provide information on land management. The nature of the soil differs from one point to another, therefore it is necessary to map the properties of the soil. The purpose of this study is to map the distribution of the properties of forest land in areas that have been degraded. The land is a former privately-owned oil palm plantation in the Gunung Leuser National Park (TNGL) forest. The study uses a continuous grid interpolation method, thus forming polygons of soil properties. The soil types are Inseptisol an Ultisol. The results of the study show that most of them belong to the type of soil that is finely textured so that erosion can easily occur if surface runoff occurs in areas that have been exposed. The soil water content range that has the widest area is the range 26.98 - 29.50% with an area of 14.38 ha (42.91% of the research area). The range of land capacity has the widest area, namely the range 42.24 - 49.32% with an area of 13.32 ha (39.76% of the research area). Low organic matter content and acidic soil pH. Based on the results of these studies, the land in the research area is less fertile. However, restoration efforts are very possible because many tree species are adaptive with low soil fertility.

Activities carried out in May-June 2018 aim to be an additional source of income to the community. Poor economic conditions are a source of declining levels of public health and education. The main problems faced by farmer group partners and village heads are: (1) community income is inadequate, (2) lack of knowledge of how to raise quail and formulation of rations, (3) partner duties as monitoring activities. The specific target of the PKM program is to create a safer and more conducive environment as an implication of the transfer of quail breeding knowledge and good ration formulation to give birth to a viable pioneer youth group who want to work and partners as monitors are expected to become new innovators independently in their environment. The methods offered: (a) Socialization of mentoring programs raising quails as an effort to convince partners to follow them, (b) Preparation of social preconditions (c) Implementation of quail farming assistance programs supported by Farmer Group Partners and Village Heads with Universities (Faculty of Animal Husbandry, Muhammadiyah University of South Tapanuli) to ensure knowledge transfer goes well and, (d) Monitoring, evaluation and reporting.  During the event the target partner has activities showed high enthusiasm, proactive conditions and discussion. Constraints arise when monitoring activities, allegedly due to the low motivation of group members, the capacity of the cage and quail transferred by the PKM Team is not enough as a fundamental motivation for members. This suspicion is reinforced by the information obtained in the field, that in general the self-help groups (Farmer / Youth / Organization / Individual Groups) in this village have been accustomed to "enjoying" social activities in the form of assistance from government and private institutions through various programs with sufficient budget big. This condition triggers "laziness" members in maintaining the transferred assets.

Perencanaan produksi dalam proses produksi manufaktur merupakan salah satu bagian dari sistemproduksi. Perencanaan produksi menentukan pengukuran kemampuan perusahaan dalam penyediaan produk.Pengaturan perencanaan produksi yang tidak baik akan menyebabkan terjadinya penumpukan (bottleneck).Bottleneck stasiun kerja mengakibatkan perusahaan tidak mampu memenuhi permintaan. PT. XYZ adalahsebuah perusahaan manufaktur dalam bidang produksi green tea yang mengalami masalah tidak mampumemenuhi permintaan akibat adanya bottleneck pada salah satu stasiun. Hal ini dapat dilihat dari jumlahproduksi green tea lebih kecil dari jumlah permintaan produk green tea. Penelitian ini bertujuan untukmenghasilkan penjadwalan produksi green tea dengan menggunakan pendekatan theory of constraint (TOC)untuk menghilangkan kendala (constraint) yang menghambat aliran produksi. Metode penjadwalan denganprinsip-prinsip dasar theory of constraint (TOC) adalah sistem penjadwalan drum buffer rope (DBR) denganmenggunkan time buffer, dimana stasiun kerja yang mengalami bottleneck diperbaiki sehingga menjadi stasiunkerja non bottleneck. Berdasarkan hasil penelitian didapatkan bahwa stasiun kerja IV merupakan stasiun kerjabottleneck. Penyebab bottleneck pada stasiun kerja IV adalah kurangnya kapasitas tersedia (CA).

Desain eksperimen adalah suatu rancangan percobaan yang dilakukan untuk mendapatkan informasi yangberhubungan dengan atau diperlukan untuk persoalan yang sedang diteliti dapat dikumpulkan. Percobaan yangdibuat adalah percobaan ekstraksi DNA bawang putih. Tujuan dari percobaan ini adalah untuk mengetahui berapabanyak takaran garam, sabun, dan kadar alkohol yang efektif agar menghasilkan volume DNA bawang putih yangsebanyak mungkin untuk keperluan medis lanjutan, seperti klonning, untuk menangani kelainan-kelainan genetik danpenemuan obat-obat baru, pada bidang pertanian, peternakan, kehutanan untuk meningkatkan produk-produk baiktanaman maupun hewan unggul maupun di bidang lingkungan dalam hal mengatasi polutan serta perannya dalamkemajuan produksi pangan. Data diperoleh dari percobaan yang dilakukan dengan melihat berapa banyak volumeDNA bawang putih yang keluar. DNA bawang putih yang diamati berupa benang-benang putih dan halus yangmengapung ke permukaan cairan. Volume yang didapat merupakan data primer yang akan digunakan untukpengolahan data keterkaitan antara taraf faktor jumlah garam, jumlah sabun, dan kadar alkohol terhadap volumeDNA bawang putih yang dihasilkan. Hasil pengujian kenormalan data dengan uji Anderson Darling maka diperolehbahwa nilai p-value=0,2540 sedangkan α = 0,05 sehingga data yang didapat berdistribusi normal. Dalam pengujianhomogenitas varians terhadap jumlah sabun, jumlah garam dan kadar alkohol dapat digunakan uji Bartlet. Pengujianhomogenitas varians melalui uji Bartlett, diperoleh bahwa varians untuk interaksi faktor jumlah sabun, jumlahgaram, dan kadar alkohol adalah sama. Hasil perhitungan ANAVA menunjukkan untuk setiap perlakuan didapatkanHo diterima yang artinya setiap taraf faktor tidak memberikan efek signifikan terhadap perubahan volume DNAbawang putih. Persamaan regresi yang digunakan adalah regresi linear berganda, sehingga diperoleh persamaanregresi Y = 9,367+ (-0,079)X1 + 0,975 X2 + 0,625 X3. Dari perhitungan persamaan regresi didapat untuk hubunganjumlah sabun(X1), jumlah garam(X2), dan kadar alkohol (X3). Koefisien korelasi antara jumlah sabun (X1) denganperubahan volume DNA bawang putih (Y) sebesar -0,8679 yang artinya bahwa untuk faktor jumlah sabun memilikihubungan terbalik terhadap perubahan volume DNA bawang putih. Sebaliknya, koefisien korelasi jumlah garam (X2)dan kadar alkohol (X3) dengan perubahan volume DNA bawang putih (Y) didapatkan sebesar 0,411 dan 0,2635 yangartinya bahwa untuk faktor jumlah garam memiliki hubungan searah dengan perubahan volume DNA bawang putih.

Peningkatan kinerja perusahaan merupakan suatu keharusan bagi perusahaan agar dapat berdaya saing. Dalam meningkatkan kinerjanya perusahaan dituntut membekali karyawannya supaya semakin terampil dalam bekerja. Untuk meningkatkan keterampilan kerja karyawan salah satunya dapat dilakukan dengan pelatihan. Penyelenggaraan pelatihan dikatakan berhasil jika berdampak bagi peningkatan keterampilan kerja karyawan yang pada akhirnya juga meningkatkan kinerja. Ada empat faktor yang mempengaruhi keberhasilan pelatihan, yaitu: instruktur pelatihan, bahan pelatihan, metode pengajaran, dan fasilitas pelatihan. Penelitian ini ingin mengetahui dampak pelatihan terhadap keterampilan kerja dan kinerja. Untuk mengetahui dampaknya dilakukan evaluasi pelatihan. Evaluasi diawali dengan menyusun instrumen penilaian kemudian dilanjutkan dengan penilaian dalam lima tahapan, yaitu: 1) evaluasi penyelenggaraan pelatihan, 2) evaluasi proses pembelajaran, 3) evaluasi aplikasi pada pekerjaan, 4) evaluasi dampak bagi kinerja perusahaan, dan 5) evaluasi dampak biaya pelatihan dengan pendapatan perusahaan. Data penelitian diperoleh dari penyebaran kuesioner terhadap 68 karyawan yang mengikuti pelatihan, pengumpulan dokumen dan laporan perusahaan. Hasil penelitian menunjukkan bahwa komponen pelatihan yang mempengaruhi keterampilan kerja adalah instruktur pelatihan (0,277), bahan pelatihan (0,575), metode pengajaran (0,545), dan fasilitas pelatihan (0,423). Hal ini sesuai dengan hasil evaluasi yang menunjukkan bahwa peningkatan rata-rata instruktur pelatihan 2,5%, bahan pelatihan 3,5%, metode pengajaran 1,8%, dan fasilitas pelatihan 3,9% tiap tahunnya juga meningkatkan keterampilan kerja sebesar 0,4%. Dari uji statistik diketahui bahwa keterampilan kerja mempengaruhi kinerja sebesar 0,282. Namun, berdasarkan hasil evaluasi diketahui bahwa pelatihan yang mempengaruhi keterampilan tidak berpengaruh terhadap kinerja. Peningkatan keterampilan kerja sebesar 0,4% tiap tahunnya, menghasilkan kinerja yang fluktuatif tiap tahunnya.
