Abstract

ABSTRACKThe aim of study is to determine the diversity og gastropods and bivalves in mangrove forests of Mendalok Village, Sungai Kunyit Subdistrict, Mempawah Regency, West Kalimantan Province. This study was conducted for 3 months was divided by using Purposive Random Sampling. Sampling sites into 3 stations, station1 was dominated by Rhizophora, station 2 was dominated by Bruguiera, anda station 3 was dominated by Nypah. Data collected in this study are primary and secondary data. The primary data was obtained through direct measurement at the study stations. This data includes number individuals per-plot, gastropods and bivalves species name, and aquatic environmental characteristics (i.e. temperature, pH, salinity, and substrat). While secondary data was obtained from village profiles. Which were 9 other species groupied into 3 families which were classified into the Gastropod class and 3 other species groupied into 1 family which were classified into the Bivalve class. From all 3 stations, species Cerithidae cingulata (Gastropods class) with the value of Abundance (K) was 24,00 ind/m2. While species Polymesoda erosa (Bivalves class) with the value of Abundance (K) was 2,00 ind/m2.Keyword : Type Composition, Cerithidae ciungalata, Polymesoda erosa

Abstract

ABSTRACTThis study aims to find the best compost dose of corn waste on the growth and yield of vigna sinensis plants on alluvial soil. The research was carried out from 25 January 2019 - 21 March 2019. The research was conducted on Jl. Purnama Agung VII, Komplek Pondok Agung Permata, Parit Tokaya Village, South Pontianak. The method used was a Completely Randomized Design (CRD) consisting of 5 treatments, 5 replications and each replication there were 4 plant samples. The following treatment p1 = 5 tons compost of corn waste / ha or equivalent to 100 gr / polybag, p2 = 10 tons compost of corn waste / ha is equivalent to 200 g / polybag, p3 = 15 tons compost of corn waste / ha equivalent to 300 g / polybag , P4 = 20 tons compost of corn waste / ha is equivalent to 400 g / polybag, P5 = 25 tons tons compost of corn waste / ha is equivalent to 500 g / polybag. The variables observed in this study were Root Volume (cm3), Chlorophyll Leaf Level (spad unit), Plant Dry Weight (g), Fruit / Plant (fruit) and Fruit Weight / Plant (g). The results showed that the best compost of corn waste for growth and yield of lvigna sinensis was 400 g / polybag, equivalent to 20 tons / ha but the variable fruit weight of pods per plant was not significant at a dose of 100 g / polybag or equivalent to 5 tons / Ha. Therefore, in this study, the effective dose of corn waste compost was found to be100 g / polybag, equivalent to 5 tons / ha.Keywords: Alluvial, Corn waste compost, vigna sinensis.

Abstract

The aim of this research was to find the drying rate of sago starch using greenhouse-effect dryer based on layer thickness and stirring frequency. This research used explorative experimental design consist of no-material treatment, 1 cm thickness with stirring frequency of 0, 2, and 4 times/hour, and 2 cm thickness and stirring frequency of 2 and 4 times/hour.  Observed parameters were sun radiation, dryer temperature, air humidity, drying rate, and material moisture content. The acquired data were analyzed descriptively. Sago starch drying showed drying rates as follows, thickness of 1 cm without stirring had drying rate of 1.39 kg/hour, thickness of 1 cm with stirring frequency of 2 times/hour had drying rate of 1.22 kg/hour, thickness of 1 cm with stirring frequency of 4 times/hour had drying rate of 1.67 kg/hour, thickness of 2 cm with stirring frequency of 2 times/hour had drying rate of 1.85 kg/hour, and thickness of 2 cm with stirring frequency of 4 times/hour had dring rate of 1.91 kg/hour.

Abstract

Gambut adalah jenis tanah yang terbentuk dari akumulasi sisa-sisa tumbuhan yang setengah membusuk sehingga kandungan bahan organiknya tinggi. Gambut terbentuk dari bagian-bagian tumbuhan yang jatuh akan tetapi proses pembusukannya terhambat.Tanah gambut menempati 47,8% dari lahan rawa di Indonesia yang luasannya sekitar 15 juta Ha dan tersebar pada empat pulau besar di Indoneaia yaitu, Sumatera, Kalimantan, Sulawesi dan Irian. Pemanfaatan lahan gambut sebagai lahan pertanian bukanlah hal yg baru, secara tradisional masyarakat telah lama memanfaatkan lahan gambut untuk usaha pertanian dalam skala kecil. Penelitian ini bertujuan untuk mengetahui Karakteristik kimia tanah (pH, KTK, N- total, P-total dan KB) pada empat jenis penggunaan lahan yaitu karet, sawit, nanas dan semak belukar di Desa Mega Timur Kecamatan Sungai Ambawang Kabupaten Kubu Raya.          Lokasi penelitian berada di lahan gambut milik rakyat dengan empat jenis penggunaan lahan diantaranya kebunan kelapa sawit, kebunan karet, kebunan nanas dan semak belukar di Desa Mega Timur Kecamatan Sungai Ambawang Kabupaten Kubu Raya.Pengambilan sampel tanah dilakukan secara komposit dengan dua kedalaman 0-30 cm dan 30-60 cm, pada masing-masing lokasi (penggunaan lahan).          Hasil analisis reaksi tanah (pH) pada empat jenis penggunaan lahan yaitu kebun nanas, kebun kelapa sawit, kebun karet dan semak belukar memiliki pH dengan kriteria sangan masam. Hasil analisis N-total dengan kriteria sedang sampai tinggi. Hasil analisis P-total termasuk dalam kriteria sangat rendah sampai tinggi. Hasil analisis K-total dengan kriteria sangat rendah. Hasil analisis KTK dengan kriteria sedang sampai tinggi. Hasil analisis KB dengan kriteria sangat rendah. Hasil analisis bobot isi pada empat jenis penggunaan lahan rata-rata sangat rendah.

Abstract

ABSTRACT Catfish (M. castaneus) is one of fresh waterfish that has considerable potential for of consumption and processed fish.Management of catfish resources needs to be done, given its existence which is increasingly difficult to obtain in nature. This study aims to examine the biology of fish reproduction that includes sex ratio, gonad maturity level and fecundity. The method used in this research was purposive sampling. The Sampling was divided into three stations, that at station I wich  on the Upper Telabang River, station II was adjacent to oil palm plantations, station III was at down stream at the intersection with Lake Terentang. The  Sampling was done 3 times on basis biweekly from Desember 2018 to June 2019. Based on the results of the study, 277 fishes was obtained, consisting of 122 males and 155 females. The sex ratio of male and female baung fish is 1:127, wich it was balanced in the Telabang River Waters. The size of the length of the sex ratio in this study ranged from 62-141 mm. The maturity study was found in the rainy season generally in TKG I and TKG II in December 2018-April 2019 and in the summer (transition) dominated by TKG III and IV in May-June 2019. Total fecundity  as a whole ranges from 5,600-43,223 eggs with a length range between 85-141 mm and weighs 7-28 g. Baung fecundity has a close relationship between total length and total weight.Keywords: Fecundity, Gonad Maturity Level, Sex Ratio.

Abstract

The purpose of this research is to know the best ratio based on the combination of the bagasse and banana “kepok” peels to the used palm oil purification. This research used Randomized Block Design one factor, the ratio formula of the combination bagasse and banana “kepok” peels (7 times treatment that is control, 0:100, 20:80, 40:60, 60:40, 80:20, and 100:0, 4 times replication). The data analyzed by ANOVA 5%, if there is significant treatment, then it continued by Turkey’s (HSD Test). Data from hedonic analyzed by Friedman test. The result showed the combination of bagasse and banana “kepok” peels at ratio 100:0 is the best treatment. The quality of used oil are moisture content 0.35%, FFA 0.96%, relative density 0.956 g/mL, saponification 167.85 mg KOH/g and viscosity 0.56 cps. Organoleptic evaluation best result is colour 1.24 (yellow clear to bit yellow) and smell 1.4 (no rancid to bit rancid).
